Abstract

Passive Q-switching of a compact $Tm : KLu {({WO}_{4})}_{2}$ microchip laser diode pumped at 805 nm is demonstrated with a polycrystalline ${Cr}^{2 +} : ZnS$ saturable absorber. This laser generates subnanosecond (780 ps) pulses with a pulse repetition frequency of 5.6 kHz at 1846.6 nm, the shortest pulse duration ever achieved by Q-switching of $\sim 2 μm$ lasers. The maximum average output power is 146 mW with a slope efficiency of 21% with respect to the absorbed power. This corresponds to a pulse energy of 25.6 μJ and a peak power of 32.8 kW.
